I’m waiting for Daniel to get back to me but this article from 2010 explains it as well.

“While the program succeeded in encouraging Democrats and environmentalists to lower their consumption, Republicans had the opposite reaction. When told of their relative thrift, they started cranking up the thermostat and leaving the lights on more often.”

A program designed to reduce energy consumption persuaded some Republicans to consume more.

This seems to explain so much of what we fight about in politics; I’m surprised it hasn’t been brought up more in public policy.
